Panels on side of shop

[DefyTheGrid]

Howdy all, Let's say I have 16 solar panels, but 4 of the panels need to go on the side (verticle) of the shop. In a 4s2p system (lv6548 inverter with two inputs), is that an ok thing to do without systemic future problems? In July, the side of the shop will not get any sun.

Explained another way

Series 1: 4 panels -> Parallel to lv6548
Series 2: 4 panels

Series 3: 4 panels -> Parallel to lv6548
Series 4: 4 panels (this series is on side of shop)

Is there anything wrong with this?

4s on roof, paralleled with 4s on wall, is fine.
Despite what practically everyone says, strings connected in parallel do not have to be of same orientation.
Panels connected in series do have to be of same orientation.

SMA did a field study of that, conclude about 2% less power produced compared to separate MPPT for each string orientation.

Only thing i would add is make sure to mount them for adequate air space between panel and building exterior or they could overheat.

Thank you so much, these installers are very incompetent. Glad I asked

Great advice - I'll make sure to do that.
